In this lab report, students conduct an egg drop experiment to understand the concepts of potential and kinetic energy, gravity, and Newton's laws of motion. The goal is to build a protective package for an egg that can withstand falling from a certain height without breaking. a detailed explanation of the experiment, including the initial package design, calculations, and procedures. It also discusses the importance of the experiment in science education and its real-world applications.

The Classic "Egg-Drop" experiment has been a standard in science instruction for many years. Essentially, students are asked to construct some type of container that will keep a raw egg from cracking when dropped from ever-increasing elevations. These kinds of experiments were inspired by none other than Sir Isaac Newton. According to Isaac Newton, “If a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.” When the egg is high, the egg is at potential energy, which is the energy associated with height. The more height was added, the potential energy will convert into kinetic energy. So when the egg impacts into the ground, the egg will be busted. This experiment is not just an experiment that students compile just to pass. This challenge or experiment also consists of fun and a lot of experience, even if it was risky to do. This challenge was used by NASA, the scientist in NASA had to build a lander for the Mars Exploration Rover. Physically, it had to withstand both the heat of entry into the Martian atmosphere and the impact of landing. Strategically, they also had to figure out a way that the rover could right itself no matter how it landed.
Conducting experiments usually starts with a problem and ends with a problem until it comes up with a solution. Notice the packaging, the materials used were visibly absorbent such as newspaper or paper, thread and glue. In addition, this season is known as the rainy season “habagat season” whereas the rain is above normal. Moreover, this day was not applicable to do an outside experiment due to pandemic, weather and poor internet connection. On the contrary, the goal of this experiment was not to bust an egg while falling down to a certain height. As a Biology Student, we find ways on how to conduct an experiment amidst the problems and hardships that the students came through. There were some tips or basic ways to increase the likelihood of an egg to survive. First is to lessen the speed. With the help of a parachute, it decreases the potential energy that was converted into kinetic energy. In addition, put a cushion inside the package where the egg was in there. Such as an airspace, This air space forms when the contents of the egg cool and contract after the egg is laid. It accounts for the crater you often see at the end of a hard-cooked egg. Upon impact the heavier spherical yolk continues moving towards the ground. The compression of the airspace acts like an airbag for the eggs' valuable contents. Building an artificial cushioning device will also help absorb the impact of landing. Also, it acts as an air bag inside the packaging so that the egg would not be busted inside the packaging. Furthermore, orient the egg so that it lands on the hardest part

When you’re trying something or experimenting something new, there are tendencies that your product or hypothesis may not be right or not accurate. Maybe it will exceed or inadequate. You’ll try again and again until you will get a great and accurate outcome. At first, our package didn’t according to plan due to there were no airbags or air sacks that will provide a safe space for the egg and will not come out in our package. Until we came up for a better idea that maybe, the egg will need a soft barrier so that it will not be busted when we try our experiment. An increased surface area on the carrier, such as a flying disc shape or a parachute, will cause the egg to hit the ground at a lower speed. To increase the time over which the egg comes to rest, Also, a sponge or other cushion in their carrier will keep the egg from stopping instantly when it hits the ground; the egg will continue its motion for a few nanoseconds, decreasing the force. In the end, it went well and the egg didn’t break even we try it at 11.5 ft or 3.5 m high. Procedures:

List 3 physics concepts; explain how they are involved in the packaged egg drop competition and reference source.
1. Gravity
According to dictionary, Gravity is the natural force that tends to cause physical objects to move towards one other. When an object is dropped, gravity causes it to fall to the Earth. The experiment demonstrated how gravity works, by dropping the packaged egg from a certain height with a certain amount of force. When the package strikes the ground, the Earth applies the same force back to the package. The higher the force, the quicker the package falls. If too much force is applied, the egg shell inside the package will break. To protect the egg from shattering, it must reduce the force applied to the package as it hits the ground.
2. Law of Inertia (Newton’s First Law of Motion) Newton’s first law or law of inertia stated that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force. Hence, when the packaged egg is elevated, it is experiencing potential energy, which is the energy that is associated with the certain height. The more height is added, the more potential energy will be converted into kinetic energy. As a result, when the packaged egg falls to the ground, the egg inside will be shattered. 3. Newton’s Second Law of Motion Newton's second law indicates that the magnitude of a force is proportional to the mass and acceleration of the object exerting the force. The second law was applied because of the acceleration generated by natural forces as the
